Here's the log of a couple of long sleeps:

pmset -g log|grep -e " Sleep " -e " Wake "

please also check : https://github.com/jkbuha/XPS-9500-IceLake-OpenCore and the issue at your repo : thaiiy#2 - that repo from jkbuha is likely the most active one regarding sleep issues and I am working on it to get it working with all models, since they are so similar.

As written, S3 sleep 'just works' when the laptop is plugged in ( for me including current BIOS ) - it just doesn't work when unplugged from power. That condition by itself is a good hint towards a potential fix.
Dell has after another support request answered they only support modern standby, which is crap and even on windows unusuable on my model. Let's join forces and fix this ourselves :).

If you read this, please test with both power brick plugged in and not and let us know if your sleep works in both cases and dump the output of sudo pmset -g

Thank you!
